PITTSBURGH — Rockies right-handed closer Wade Davis is going on the 10-day injured list with a left oblique strain, the team announced Wednesday.

He’ll be replaced in the bullpen by hard-throwing righty Jairo Díaz, who has battled injury and personal tragedy to make it back to the big leagues. Diaz was called up from Triple-A Albuquerque and added to the 40-man roster.

According to head trainer Keith Dugger, Davis’ oblique injury is not considered severe. Davis’ stint on the IL is retroactive to Sunday but there is no timetable for his return.

Manager Bud Black said that right-hander Scott Oberg, who’s served as Colorado’s primary set-up man, will be the primary closer in Davis’s absence. Oberg has been sharp, posting a 1.77 ERA over 18 appearances, with a .186 batting average against. Oberg’s weakness has been control. He has 11 walks vs. 13 strikeouts.

In addition to its bullpen shuffle, the club announced that left-handed starter Tyler Anderson, who’s scheduled to undergo surgery on his ailing left knee, was recalled from Triple-A and placed on the 60-Day IL. There is no date set for Anderson’s surgery.

Diaz, who turns 28 on Monday, has pitched exceptionally well at Triple-A, going 1-0 with six saves, a 0.45 ERA over 20 innings, with 22 strikeouts vs. only six walks. Opponents have hit just .171 average against him.

“His command has been good — strikeouts are up and walks are down,” Black said.

Diaz, a fastball-slider pitcher who’s fastball velocity sits at 95-96 but still touches 100 mph on occasion, is in a good place after a difficult road back to the majors.

Diaz missed the entire 2016 season because of Tommy John surgery on his right elbow. He appeared in just four games for Colorado in 2017, but in addition to trying to rehab his arm, he was dealing with a tragic family issue. His wife, Dubraska ‘Duby’ Daiz, fought a lengthy battle with stomach cancer that eventually took her life at age 30. She died on Oct. 22, 2017. Diaz has raised their daughter, Hannah, ever since as a single dad, with help from his family.

Added Black: “It’s a great day for all of us, to know what he went through and see this. There is some tragedy there. But now, to be back here with us, it’s an uplifting thing for all of us. I’m so happy for him.”

Davis, 33, is on the injured list for the first time since 2016 when he pitched for Kansas City. He was off to a strong start this season, posting a 2.45 ERA with seven saves. He’s struck out 18 while walking 10 and has not allowed a home run since Aug. 12, making his streak of 32 ⅔ innings without allowing a home run the second-longest active streak in the National League.

The Rockies officially described Anderson’s injury as a left knee chondral defect. Dugger said it is a chronic injury, not the result of a single traumatic event, such as a torn knee ligament. The knee tissue in question is the articular cartilage. According to the Steadman-Hawkins Clinic website, articular cartilage is the shiny, white surface that covers the ends of most bones. Articular cartilage protects the ends of bones and allows the joints to glide smoothly with less friction. It also helps to spread the loads applied to a joint.

This is not the Jordan Lyles that Rockies fans were used to seeing when he pitched for Colorado from 2014 into 2017, a time when his ERA got progressively worse. He has been reborn in Pittsburgh, as evident from his last start at San Diego when he pitched seven innings, giving up one run on five hits and one walk while striking out a career-high 12. “It was complete command from start to the end,” Pirates manager Clint Hurdle told reporters. “I think he retired nine guys on three pitches or less. It was just a really well-pitched game. He just continues to show us good stuff. He’s building some street cred a lot of different places.” Senzatela, who’s added a changeup to his pitch mix, has pitched well in two of his last three starts.

Trending: Entering Wednesday night’s game, Nolan Arenado and Charlie Blackmon were among only six National League players — and the only set of teammates — batting over .300 with at least 10 doubles and 10 home runs this season.

At issue: The Rockies need to find a stable starter to replace left-hander Tyler Anderson, who was placed on the 60-day injured list Wednesday. The Rockies hope right-hander Jeff Hoffman, the centerpiece of the Troy Tulowitzki trade in 2015, will be able to fill the bill. Though Hoffman has shown some promise at Triple-A Albuquerque this month, his big-league numbers are not good: 6-10, 5.92 ERA and 1.580 WHIP in 38 games (24 starts).
